通过激光散射技术,测量了离心喷嘴下游液雾特性(液雾平均尺寸、尺寸分布指数)沿径向距离及沿倾斜方向的变化,建立了相应的物理模型,进行了计算。计算结果与试验数据相符很好,表明本文提出的模型的合理性。 The laser scattering technology was used to measure the variation of the liquid mist characteristics (mean size and size distribution index) of the centrifugal nozzle along the radial direction and along the inclined direction. The corresponding physical model was established and calculated. The calculated results are in good agreement with the experimental data, indicating the rationality of the proposed model.
